Hi, I am new to use SU. And it is first time to install the program. But there is a problem to use this. When I started SU, there was a pop-up “The Sketch up application’s operation stopped”. I’ve already tried to reinstall SU, but It has same problem. My graphics card is ‘Intel® HD Graphics 4600’ and Nvidia Geforce 840M’. And other installed 3d modeling program is CATIA and auto 3D max. after this problem, I deleted auto 3D max. But It doesn’t still operate. What can I do? Help me Please.

Is your Graphics Card [Geforce] set up to be the default card used by 3d apps like SketchUp ?
It is likely to be superior to the Intel one.
What’s its RAM ?
Are its drivers up to date ?

Also, when you install SketchUp you must find its installer exe file icon [probably in your Downloads folder], select it, right-click > context-menu > "Run as administrator"
Launching it any other way - e.g. by picking “Run” or double-clicking the icon will not install it properly; even if you have admin-powers.
You can repeat this installation process to try and ‘repair’ it.
Run as administrator as explained above, when prompted choose “Repair”.
Retest…
If that doesn’t succeed repeat the process but choose “Uninstall”, then “Reinstall” again…
